A computational optimization approach to scoliosis brace design – Preliminary results
(orthopaedic research society, 2022) Kardash, Kateryna; Rodriguez, Jesus P.; Otaduy, Miguel A.
The design of braces for adolescent idiopathic scoliosis is a problem that could potentially benefit from computational solutions. There is a broad body of research on simulation of the human spine, including simulation of scoliosis, as well as braces and their effects on the body. Some sparse works leverage these simulation models to evaluate the quality of digital brace designs, but the computational approach to scoliosis brace design remains largely underused.
Simulation-Based Morphing of Personalized Models of the Torso for Scoliosis Brace Design – Preliminary Results
(orthopaedic research society, 2022) Koutras, Christos; Shayestehpour, Hamed; Rodriguez, Jesus P.; Rasmussen, John; Wong, Christian; Otaduy, Miguel A.
Computational and personalized design of braces for patients suffering from adolescent idiopathic scoliosis is a subject that has not been extensively studied and faces several unknowns. One of the most challenging tasks is the development of patient-specific biomechanical models of the torso. The first step required in order to build a personalized model is the acquisition of the patient’s specific geometry, i.e., the bones and joints of the skeleton. To this end, this study morphs a template torso model into patient-specific data in the following way: We start by acquiring x-rays, and we annotate personalized landmarks. Then, we use as template a biomechanical torso model consisted of a multibody dynamic system coupled with FEM and we proceed to the morphing in two steps. First, an initial tuning by adjusting the global scale of the model and finally a finer one, taking into account local deformations.
